Symptoms

  • MIL illuminated
  • Possible smell of unburnt fuel or reduced performance in severe cases

Possible causes

  • Aged or damaged catalytic converter
  • Downstream oxygen sensor fault giving a wrong efficiency reading
  • Exhaust leak
  • Misfire or mixture fault overloading the catalyst

Recommended checks

  • Compare upstream and downstream oxygen sensor signals
  • Check for exhaust leaks
  • Check for stored misfire or mixture codes first
  • Verify catalyst temperature plausibility where available

Can TuningBot remove P200F at file level?

If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry and, where the ECU needs it, corrects the checksum too. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
